Kinematic Gait Adjustments to Virtual Environments on Different Surface Conditions: Do Treadmill and Over-Ground Walking Exhibit Different Adaptations to Passive Virtual Immersion?

Figure 4

Comparative analysis of the COM excursion angle in response to the first exposure to the VRE for both over-ground and treadmill surface conditions. (a) Mean and SD of the COM excursion angle for the first natural walking (NW_OG) trial and the first snowy () VRE trial during over-ground walking. (b) Mean and SD of the COM excursion angle during the first natural walking (NW_OG) trial and the first crowded () VRE trial during over-ground walking. (c) Mean and SD of the COM excursion angle for the first natural walking (NW_TM) trial and the first snowy () VRE trial during treadmill walking. (d) Mean and SD of the COM excursion angle for the first natural walking (NW_TM) trial and the first crowded () VRE trial during treadmill walking. Significant changes between trials () are indicated by .
